Description

COMPOSITION FOR CLEANING SKIN STRIPS OF SKIN SKIS
FIELD OF THE INVENTION
The present invention relates to a composition for cleaning skin strips of skin skis, and more particularly to a composition free of any aliphatic and/or aromatic hydrocarbons for removing hydrophobic compounds such as oils, resins, grease, and/or waxes from the surface of skin strips.
BACKGROUND OF THE INVENTION
Skin strips, also referred to as climbing skins or ski skins, are strips that attach to the bottom of Nordic and Alpine skis to provide grip. To provide waxless skis skin strips are typically attached to the kick zone of the skis with an adhesive on the ski base thus providing skin skis. They are called skins because they resem-ble sealskin and are designed to let the ski slide forward on snow but not backward and to provide solid grip. They are typically made from mohair or nylon or a com-bination thereof. They may also be coated with e.g. teflon.
The skin strip surface should be cleaned periodically to provide suffi-cient grip and smooth forward slide. Typical compositions marketed for cleaning ski bases consist of or contain major amounts aliphatic hydrocarbon solvents such as heptane. Cleaning composition based on aliphatic and/or aromatic hydrocar-bons unfortunately dissolves the adhesive attaching the skin strips to the ski base and when employed for cleaning skin strips leads to detachment of the skin strip from the ski base. This naturally leads to the damage of the ski.

for cleaning skin strips, in particular for removing hydrophobic coin-pounds, such as oils, resins, grease, and/or waxes, from the surface of the skin strips.
The term "skin strip" refers to strips that may be attached to the bottom of Nordic or Alpine skis to provide grip, in particularly to strips attached to the kick zone of the skis with an adhesive on the ski base. The said skin strips are preferably comprised from mohair, nylon or a combination thereof. They may also be coated with e.g. teflon.
The term "comprise" as used herein and hereafter describes the constit-uents of the present composition in a non-limiting manner i.e. the present compo-sition comprising defined constituents consists, at least, of the said constituents, but may additionally, when desired, comprise other constituents. However, the present composition comprising defined constituents may consist of only the said constituents. The term "comprise" is further used to reflect that the present com-position may comprise trace amounts of other materials or impurities, or both, which do not alter the effectiveness of the present composition.
The present composition preferably does not comprise aliphatic and ar-omatic hydrocarbon solvents as their presence even in small amounts could lead to detachment of the skin strip from the base of the ski.
The present composition comprises (a) Ci-6_a1c0h01(s), preferably C2-4-alcohol(s) as a solvent. The term "C1-6_a1coho1" refers to alcohols comprising a C1-6-alkyl group and a OH-group attached to the alkyl group. The Ci-C6-alkyl group of the Ci-6_a1coho1 may be linear or branched. Examples of Ci-6_a1c0h01(s) include methanol, ethanol, n-propanol, i-propanol, n-butanol, i-butanol, t-butanol, penta-nol, hexanol, etc. Preferably (a) the C1_6-alcohol is selected from a group consisting of ethanol, propanol, and any mixtures thereof.
4 PCT/F12017/050095 The above described (a) Ci-6_alcohol(s) are typically present in the com-position in an amount from 60 to 90% by weight, preferably from 70 to 85 % by weight, of the total weight of the composition. The amount of (a) is dependent of the amount of the other components in the present composition. Most preferably the amount of (a) is 80% by weight of the total weight of the composition.
The present composition also comprises (b) dibasic ester(s) of formula (I). Preferably the ester parts the dibasic ester(s) are derived from methanol (i.e.
Ri is methyl) thus providing dibasic methyl esters. However, also esters with longer alkyl chains can be employed. The acid core of the dibasic ester(s) is prefer-ably derived from a linear C2_4-dicarboxylic acid (i.e. n is 2 to 4).
Preferably the di-basic ester(s) of formula (I) (b) are selected from a group consisting of dimethyl succinate, dimethyl glutarate, dimethyl adipate, and any mixtures thereof.
The above described dibasic ester(s) of formula (I) (b) are typically pre-sent in the composition in an amount from 10 to 30% by weight of the total weight of the composition. The amount of (b) must be sufficient to provide effective clean-ing of the skin strips. Preferably the amount of (b) is 12 to 25% by weight, more preferably 15 to 20% by weight, of the total weight of the composition.
In addition to (a) alcohol(s) and (b) dibasic ester(s) the present compo-sition advantageously comprises (c) up to 5% by weight of the total weight of the composition of alkoxy-alkanol (s) of formula (II) R20 -(CH2).-OH (II) wherein m is 1 to 4, preferably 2 or 3, and R2 is C1_6-alkyl, preferably C3_6-alkyl;
and/or (d) up to 5% by weight of the total weight of the composition of tri(Ci_ 6-alkanol) amine (s), preferably tri (C2_4-alkanol) amine (s).
Preferably both alkoxyalkanol(s) (c) and tri(C1_6-alkanol)amine(s) (d) are present in the present composition.
Alkoxyalkanols of formula (II) (c) are particularly advantageous com-ponent of the present composition as they dissolve both water-soluble and hydro-phobic substances. Thus their presence improves removal of build up dirt from the
5 PCT/F12017/050095 surface of the skin strips. The amount of alkoxyalkanol(s) (c) in the present com-position is preferably from 1 to 5% by weight, more preferably 1.5 to 3% by weight, most preferably 2% by weight, of the total weight of the composition.
Preferably the alkoxyalkanol of formula (II) (c) is butoxyethanol.
The present composition may also comprise (d) tri(C1_6-alkanol)-amine(s), preferably tri(C2_4-alkanol)amine(s). The term "tri(C1_6-alkanol)amine"
refers to tertiary amines, wherein the nitrogen is substituted with three C1_6-alka-nol groups. The term "C1_6-alkanol" further refers to HO-substituted C1_6-alkyl groups, in particularly to groups having formula -(CH2)1_6-0H. The presence of (d) adjusts and buffers the pH of the present composition, and helps to dissolve oils, waxes and other impurities on the skin strips that are not completely soluble in water. The amount of tri(C1_6-alkanol)amine(s) (d) in the present composition is preferably from 0.2 to 5% by weight, more preferably 0.5 to 2% by weight, most preferably 1% by weight, of the total weight of the composition. Preferably the tri(C1_6-alkanol)amine (d) is triethanolamine.
Most preferably the present composition is a composition comprising (a) C1_6-alcohol(s), wherein the C1_6-alcohol is selected from a group consisting of ethanol, propanol and any mixtures thereof;
(b) 10 to 30% by weight of the total weight of the composition of dibasic ester(s) of formula (I), wherein the dibasic ester(s) of formula (I) are selected from a group consisting of dimethyl succinate, dimethyl glutarate, dimethyl adipate, and any mixtures thereof;
(c) up to 5% by weight of the total weight of the composition of alkoxy-alkanol(s) of formula (II), wherein (c) the alkoxyalkanol of formula (II) is butoxy-ethanol; and (d) up to 5% by weight of the total weight of the composition of tri(C1_6-alkanol)amine(s), wherein the tri(C1_6-alkanol)amine is triethanolamine.
Provided herein is also a method for cleaning skin strips, in particular for removing hydrophobic compounds such as oils, resins, grease, and/or waxes from a surface of a skin strip, comprising contacting the surface of a skin strip with the present composition.
The present composition may be used for cleaning of skin strips as such.
The present composition is obtained by mixing the components of the composition.
It may for example be provided in any suitable container, for example a container comprising a nozzle for pouring the composition from the container directly onto the skin strip surface. The composition is then preferably spread and rubbed on the
6 PCT/F12017/050095 whole surface of the skin strip with a clean cloth until any build-up dirt has been removed. The present composition may also be provided in a spray bottle to be sprayed on the surface of the skin strips. Alternatively the present composition may be provided in a form of a disposable cloth into which the composition has been adsorbed in an amount that is effective for cleaning the surface of a skin strip.
The disposable cloth is preferably suitably packed to prevent evaporation of the present composition prior to use.
Further provided herein is a kit for maintenance of skin strips, compris-ing a container or disposable cloth(s) comprising the present composition.
When the kit comprises a container comprising the present composition it preferably fur-ther comprises a cloth for spreading the composition on the surface of a skin strip.
The container comprising the present composition preferably comprises a nozzle for pouring the present composition from the container directly onto the surface of the skin strip. The present kit may further comprise a second container or sec-ond disposable cloth(s) comprising a composition for improving the gliding prop-erties of the skin strips on snow.
EXAMPLES
Example 1. Composition 1 80% by weight of ethanol 17% by weight of a mixture of dimethyl succinate dimethyl glutarate, and dimethyl adipate 2% by weight of ethylene glycol butyl ether 1% by wight of triethanolamine.
Example 2. Reference composition 2 90% by weight of ethanol 8.5% by weight of a mixture of dimethyl succinate dimethyl glutarate, and dimethyl adipate 1% by weight of ethylene glycol butyl ether 0.5% by wight of triethanolamine.
7 PCT/F12017/050095 The compositions 1 and 2 were obtained by mixing the above indicated components and tested for cleaning efficiency in removal of build-up dirt from a skin strip. Two skin strips attached to ski bases were deliberately contaminated with ski wax. The above described compositions were applied on the surface of dif-ferent skin strips by pouring the respective composition from a container equipped with a nozzle onto the skin strip and spread and rubbed on the whole surface of the skin strip with a clean cloth. It could be seen that the ski wax was removed from the surface of the skin strip treated with Composition 1 without detaching the skin strip from the ski base. However, ski wax was not sufficiently removed from the from the surface of the skin strip treated with Composition 2 although also in this case the skin strip was not detached from the ski base.
It will be obvious to a person skilled in the art that, as the technology advances, the inventive concept can be implemented in various ways. The inven-tion and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
